PROCESS OF MAKING MULTICOLORED FABRICS.

SPECIFICATION forming part of Letters Patent No. 689,559, dated December24:, 1901- Application filed January 5, 1899. serial No. 701,255. (Nospecimens.)

To all whomit may concern:

Be it known that I, FELIX MEYER, a citizen of the German Empire,residing at Aixla-Chapelle, Germany, have invented certain 5 new anduseful Improvements in the Manufacture of Mixed or Multicolored Yarnsand Fabrics; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The object of my present invention is a new and most simplified way forfabricating mixtures in botany, cheviot, and other woolen I yarns, aswell as multicolored twists and fabrics which contain such yarns.

While up to now mixtures were made by mixing woolen fibers of differentshades, each of which had to be dyed first, and while multicoloredtwists were fabricated by twisting threads of different shades, whichhad also to be dyed first, the new and simplified way of making thoseyarns and fabrics which contain such yarns is as follows: Woolen fiber,either wool or tops or noils or any other kind of woolen material, isprepared or mordanted, for example, by fixing chromic acid on the fiberor by any other mordanting or preparing process. Now the prepared woolen3o fiber is mixed with unprepared fiber or with fiber prepared in anyother way, and then they are spun together. For making multicoloredtwist the prepared or mordanted thread is twisted with unprepared threador with threads prepared in another way. It is advisable to give theprepared orv mordanted wool or thread a light red or blue shade in orderto have a better control over the mixing or twisting process.

0 The yarn fabricated in the above-described way is either dyed in theyarn in hanks or skeins or it is woven and then dyed in the piece. Ineither case the yarn or cloth is dyed thus: that the prepared fiber getsa shade different from that of the unprepared fiber,

as well as from that of the fiber prepared in another way, so an effectof two or more shades, according to the number of kinds of preparedfibers and unprepared fibers,is made by dyeing the aforesaid mixtures ortwists in hanks or in the piece. The dyeing is done with a combinationof coloring-stuffs which either have no effect on unprepared fibers orhave a different effect on prepared fibers and on unprepared ones orwhich dye both classes 5 5 of fibers in the same way.

Having now particularly described the nature of my said invention and inwhat manner it is to be performed, I wish it to be un derstood that I amaware that fabrics have been before made by weaving together preparedand unprepared yarns and then dyeing and that I make no claim to this;but

I declare that what I claim as myinvention, and desire to secure byLetters Patent, is-

l. The herein-described process of producing woolen and analogous goods,which consists in mordanting fibers, spinning the said mordanted fiberswith unmordanted fibers, then weaving the yarn or thread so producedinto a fabric, and finally dyeing the said fabric, thereby producingvariegated colors or shades, substantially as described.
